This invention relates to pipes for smoking tobacco and the objects of the invention are to roduce a pipe that Wlll provlde a sweet, c ean smoke at all times, to thereby obviate the breaking in and the continual cleaning so necessary, for example, to brlar and meerschaum pipes, to provide a sweet smoke.

To the accom lishment of the above ob- '1 jects and to sue others as may hereinafter appear the present invention comprises a pipe provided with a bowl having a l1ner made of carbon, the lower end of which is connected to a. metal bottom plate to which to is connected the stem of the pipe, the present" invention further comprises means. for securing the carbon liner and metal bottom plate together to form a pipe, that will not only be pleasing in appearance but will resist any ordinary wear to which the'pipe ma be subject in use.

I eferring to'the drawings: I Fig. 1 is a longitudinal section of a pipe .made in accordance with the present invention.

Fig. 2, is a side view of the pipe shown in Fig. 3 is a detail view of the metal bottom plate and connecting metal, stem.

Fig. 4 is a detail view of the liner cover.

Fig. 5 is a detail view of the liner. Fig.6 is a view of the parts of the pipe assembled in one half of a mold.

In the drawin s 1 designates the bowl of the pipe and 2 the stemportion thereof, in

- the present instance, made of a suitable composition to be presently described. e In thepresentinstance and inaccordance with the present invention the interior of rovided with a carbon liner preferabl made of wood, which covers the top and sides of the carbon liner. The bottomo 11 end of the carbon liner 4 is .ar-

rang plate .6. which is secured to one end of a stem 7, also preferably made of metal, to

- I the other end of which is removably secured a bit 8.

the liner sleeve. 5, shown in Figure 4,

the bottom plate 6 with'stem 7, shown in Fi e 3, are assembled, as just described an mold 9 as shown in Figure 6. The 0 er to be connected to a metal bottom The carbon'liner 4, shown in Figure an then inserted inone portion of a s Iiir portion of the split mold 9, not shown, is then placed in position and a suitable composition forced through-a mold opening 10, into a spacell, shaped to conform to an enlarged outline of the bowl and stem of the pipe so that when the composition dries and shrinks the bowl and stem will assume the general form and configuration shown remove any excessive cake or carbon de posit formed by smoking, a suitable metal ring 12, in the present instance corrugated, is preferably provided which is molded in the carbon liner as shown in Fi ures 1 and 5. If desired, more rings can be provided and spaced -at suitable intervals, as desired.

The liner sleeve 5 above described is preferably made of hard wood suitably formed to enclose the top and outer sides of the carbon liner 4, as clearl shown in Figures 1 and 4. The top rtion of the liner sleeve 5 is made relative y thick to be able to withstand any pounding incident to cleaning the pipe, the inner edge being undercut to protect the top of the carbon liner, the outer edge of the liner sleeve is also undercut to protect the to of the composition forming the outside 0 the bowl of the pipe.- The side wall of the liner sleeve 5 preferably. extends approximately the entire length of the carbon liner 4 to not only keep the carbon liner 4 from contact with the composition from which the carbon might absorb a disagreeable taste, but also to act as a heat insulator to prevent undue heating of the bowl of the pipe. The side wall of the liner sleeve 5 also preferably extends approximately the entire length of the carbon liner 4 in order to 'firmly hold in place the top portion of the liner sleeve 5 which is frequently subjected to hard blows as above referred to.

In order to further protect the carbon liner 4 from absorbing anything from its exterior surface that m1 ht give a disagreeable taste, the carbon or is preferably wrapped with a thin sheet of tinfoil previous to its insertion in the liner sleeve which in addition acts to make a tight fit between the carbon liner and the liner sleeve.

The metal bottom plate or bowl 6 above described is preferably made of aluminum the upper edge of which is arranged to fit inside thebottom of the carbon liner 4, as clearly shown in Figure 1, suitable lugs 13 being unched out of the sides of the bottom p ate 6 on which the bottom, of the liner 4 rests. The metal bottom' plate 'or bowl 6 is suitably connected to one end of the stem 7, preferably also made of aluminum, which is preferably bent inward as shown at 14 to form a relatively broad restricted opening to the plate or bowl 6 so as to afford an opening that will permit the pipe to draw easily and will not readily clog or stop up. The bent portion 14 of the stem 7 also affords at its top a suitable base upon which the bottom edge of the charcoal liner 4 rests. The outer end of the stem 7 is, in the present instance, made to extend be yond the end of the stem portion 2 of the pipe to facilitate the bit 8 being removably attached thereto.

The composition above referred to is preferably made of glue or gelatine (1 part) water (3-4 parts), cotton, finely cut (2 parts) and a small amount of formaline, which acts to set the composition, whereas the cotton acts as a binder to facilitate a uniform shrinkage of the composition and to lighten the same. 4

The composition above described is preferably placed in a suitable pressure gun from which it is forced under ressure through the opening 10 of the mo (1 9, as

above set forth. In the present instance the space 10 is preferably roughened as shown in Figure 6 in order to give a roughened surface to the bowl of the pipe, the roughness of the bowl being increased by shrink age of the composition in drying. The shrinkage of the composition is considerable so the space 10, as shown in Figure 6, is made appreciably larger than the shrunken or finished product shown in Figure 2. If desired the s ace 10 can be made smooth in order to pro uce a smooth surface pipe.

The composition can be suitably colored in- .serting suitable coloring matter in the mixture or by coating the surface thereof after the same is set and dried. Different colored pieces of cotton or other fabric can be used in the mixture to color the composition as may be desired.

From the above description it will be seen that the provision of the charcoal liner, referably made of wood charcoal or sim'iar charcoal, insures a sweet smoke at all times as the tobacco in burning will not burn the charcoal liner or absorb any taste from the same. The charcoal liner acts as does the carbon deposit in the bowl of a briar or meerschaum pipe formed only by continuously burning tobacco therein. Said briar or meerschaum pipes having a disagreeable taste until such *carbon" deposit or cake is formed. a

From the above description it will also be seen that the provision of the metal bottom plate or bowl, preferably made of aluminum, insures a dry smoke at all times as the tobacco in burning will heat the plate or bowl sufficiently to evaporate any moisture that may accumulate in the plate or bowl, thereby actin to keep the pipe sweet and clean with or y occasional cleanings. The ordinary briar or meerschaum pipe has to be cleaned almost continuously in order to remove this moisture which acts to foul the pipe and make smoking very strong and disagreeable.

While the charcoal liner and metal bottom. plate or bowl are secured together by means of the composition above described the same can be easily inserted for example in a briar or meerschaum pipe and as such means are simple it was not thought necessary to show any such modification.

While the invention has been described with particular reference to details, the same is not to be considered as limited thereto, as many changes can be made and still fall within the scope of the invention set forth in the following claims.

- What I claim is:

1. A pipe provided with a bowl having a liner made of wood charcoal inserted and top of said liner.

5. A pipe provided with a bowl having a liner made of carbon and means for reinforcing said carbon liner to prevent the same being cut from. the bowl.

In testimony whereof I aflix my signature.
